A review of the existing applications of geosynthetics and geosystems in hydraulic and coastal engineering, with an overview on material specifications, structural components, relevant tools during conceptual and detail design, possible applications, and execution aspects. A more detailed description is given of new or lesser-known systems and applications. Additional basic information on design methodology and geosynthetics is included to provide a basic framework of information for design purposes.
Seawall Design focuses on all aspects of seawall design, from the broader issues of coastal management and other options for coastal defense and environmental assessment, to problem definition and project planning; data collection and interpretation; conceptual and detailed design; design for construction and maintenance; and materials to be used. The reader is guided with respect to the range of potential problems, their definition, and possible solutions, as well as the key functional requirements of a seawall and the methods of design to take due account of engineering and environmental and economic considerations. Comprised of eight chapters, this book begins with an overview of the principal function of a seawall and the guidelines for seawall design covering all relevant considerations including environmental aspects, construction, and long-term management. The discussion then turns to regular monitoring of coastal management, options for coastal defense, and the impact of phased works on coastal management. Subsequent chapters deal with project planning and environmental aspects of seawall design; data collection, analysis, and interpretation; and overall concept and types of seawall structure;. Design considerations for a seawall are described, starting with hydraulic performance, the overall stability of the embankment and coastal cliffs as well as structural loads. The book concludes with an assessment of financial and economic considerations in the planning, design, construction and maintenance of seawalls. This monograph is intended for engineers involved in the planning and design of seawalls.
Challenges and Innovations in Geotechnics is a collections of papers presented at the Eighth Asian Young Geotechnical Engineering Conference (8AYGEC, Astana, Kazakhstan, 5-7 August 2016), and covers various aspects the areas of soil mechanics and geotechnical engineering. The book contains special and keynote lectures and contributions on a wide range of topics in geotechnical engineering and construction: (1) Laboratory and Field Testing (2) Foundation and Underground Structure (3) Ground Improvement (4) Earthquake and Environment (5) Numerical and Analytical Modeling (6) Advanced Soil Mechanics (7) Historical Sites Challenges and Innovations in Geotechnics was published under the auspices of the ISSMGE TC-305 ‘Geotechnical Infrastructures for Megacities and New Capitals’, and reflects the present and future state of geotechnical engineering. The book will be extremely useful to geoengineers and researchers in the abovementioned areas.
While economic and social indicators in many Middle East and North Africa (MENA) countries have improved over the past three decades, the region’s blue natural assets—clean air, healthy seas, and coastlines—have degraded virtually everywhere. Air pollution levels in the region’s cities are among the highest in the world. Per capita marine plastic pollution is among the highest in the world; coastal erosion rates are the second fastest in the world. These combined challenges threaten local communities, livelihoods, and economies. In fact, the economic cost of MENA’s deteriorating skies and seas is estimated at more than 3 percent of GDP per year. Blue Skies, Blue Seas: Air Pollution, Marine Plastics, and Coastal Erosion in the Middle East and North Africa reviews integrated solutions that the authors identify as the “four I’s†?: • Inform stakeholders about the sources of these challenges. • Provide incentives that improve environmental outcomes for the public and the private sector. • Strengthen institutions to lower air and plastic pollution and to mitigate uncontrolled development and erosion of coastlines. • Invest in abatement options and promote sustainable solutions. Restoring MENA’s blue skies and seas will benefit the health, livelihoods, and incomes of residents. There will inevitably be trade-offs, but choosing a path of green growth will create jobs, diversify economies, and make the region a better place for current and future generations. The actions of policy makers today will shape the trajectory of economies and communities for decades to come.
During the past decade, the use of geotextiles has increased significantly in a wide range of civil engineering applications: road construction, coastal engineering, stabilization of slopes and retaining structures, reinforcement of foundations, drainage etc. This work focuses on the factors which determine the level of long-term performance of these materials such as their mechanical and physical properties and physico-chemical ageing processes. (It includes contributions to an international seminar held at Saint-Remy-les-Chevreuse, France, in November 1986)
